Does it come with a battery?

No. It is a bare tool, so you need a Craftsman V20 18V lithium-ion battery and charger. Craftsman recommends a 4.0 Ah pack or larger for framing work.

What nails does it take?

It uses paper-strip full round-head framing nails up to 3-1/4 in. long. Clipped-head and loose nails are not supported.

How does it compare with a pneumatic framing nailer?

It removes the compressor and hose, which helps on roofs, decks and remote sites. Pneumatic framers still fire faster and run all day without battery changes.

Can it sink 3-1/4 in. nails fully?

Craftsman rates it to sink 3-1/4 in. full round-head nails. Depth is set with the tool-free adjustment, and an LED warns of possible motor stalls in tough material.

Is it heavy for overhead framing?

It weighs under 10 lb before the battery, which is light for a cordless framer. Adding a 4.0 Ah pack pushes it closer to pneumatic weight, so overhead work still tires your arms.

What firing mode does it use?

It fires in rapid sequential mode, where you must release and press the trigger for each nail. That is safer than bump firing but slower for high-volume sheathing.
